Days of peaceful protests devolved into riots, with assaults on police, looting, arson and the devastation of businesses.

Baltimore Mayor Catherine Pugh said in a tweet that the city is working hard to earn and maintain the trust of the public. She said she has demanded answers and accountability for what happened Saturday.

“We are working day and night to bring about a new era of community-based, Constitutional policing and will not be deterred by this or any other instance that threatens our efforts to reestablish trust of all citizens in the Baltimore Police Department,” she said.
